  In the literature, there is no longer agreement neither on the real existence neither on the pathogenicmechanism that causes ligamentous lumbar stenosis or “soft stenosis”. In particular, the main questions are: 1 – is it caused by the hypertrophy of the ligamentum flavum or by its withdrawal into the spinal canal due to the loss of elasticity and the disc collapse? 2 - is there a molecular substrate that can explain the hypertrophy of the ligamentum flavum? Lately, the identification of the fractalkine’s overexpression demonstrated a fundamental role of the metameric instability and of the joint inflammation in the pathogenesis of hypertrophy of the ligamentum flavum, thus making clear the association between joint hypermobility and soft spinal stenosis. The study of this association is worthy of more clinical and instrumental findings, even if recen.. Read More»
